From the computation, the magnitude of the drag force when the skydiver reached terminal speed is 784 Newtons.
From the complete information, the skydiver has a mass of 80kg and jumps off a plane. The free-fall acceleration is also given as 9.80m/s².
Therefore, the weight of the skydiver will be:
W = mass × acceleration
W = 80 × 9.80
W = 784N
In conclusion, the magnitude of the drag force due to air resistance is 784N.
